Effect of porosity parameters on the static buckling behavior of FGP plates using the Ritz method and first-order shear deformation theory

Tóm tắt

This study investigates the static buckling behavior of functionally graded porous (FGP) plates. A theoretical model is developed based on the first-order shear deformation theory (FSDT), while the Ritz method is utilized to solve the governing equations. In this model, the material properties are considered to vary continuously through according to three distinct porosity schemes, including uniform, symmetric, and asymmetric distributions. The validity and accuracy of the developed model are confirmed by benchmarking the results against available data reported in the literature. A comprehensive numerical study is carried out to explore the effects of key parameters, such as porosity characteristics (distribution patterns and coefficients) and geometric properties, on the critical buckling load. The outcomes of this investigation contribute to a better understanding and serve as a valuable resource for the design and optimization of engineering structures fabricated from advanced functional materials.
